SPECIFICATION forming part of Letters Patent No. 302,798, dated July29,1884.

Application filed March 1, 1884, (No model.)

To all whom, it natty concern:

Be it known that I, J UDSON L. THOMSON, of Syracuse, in the county ofOnondaga, in the State ofNcw York, have invented new and usefulImprovements in Shoe-Clasps, of which the following, taken in connectionwith the accompanying drawings, is a full, clear and exact description.

This invention relates to the class of shoeclasps in which aspringaetuated tongue interlocks with a slotted plate.

The invention consists in eorrugating the slotted plate transversely andforming the tongue with corresponding corrugations adapted to liecontiguous to the aforesaid plate, thereby affording to the tongue afirmer interlocking hold and rendering the clasp strong and compact.

The invention is fully illustrated in the annexed drawings, whereinFigure l is an edge view of the clasp with the parts interlocked. Fig. 2is a plan View of the same, and Figs. 3 and 4 are isometric views of theparts detached.

Similar letters of reference indicate corresponding parts.

A and B are two metal plates adapted to be attached to the two quaitersof an arctic overshoe. Theplate B is corrugated transversely, and isprovided with a series of transverse slots, d (1, preferably on thatside of the raised portions of the corrugations which faces the lixedend of the plate. The plate A has atits I free end two raisedeoncavo-eonvex bearings for the pintlc of the tongue T, which is hingedbetween said bearings. A spring, 8, connectautomatically force the saidtongue into the twoextremes of its movement. The tongueT is corrugatedtransversely, corresponding to the corrugations of the slotted plate B,so that when said tongue is inserted through one of the slots d andturned down into its interlocking position it will lie contiguous to thetop of the corrugated plate B, as represented in Fig. 1 of the drawings,thereby rendering the clasp compact and re-enforcing the hold of theinterlocking parts.

NVhat I claim as new, Letters Patent, is

The combination of the plate B, corrugated transversely, and providedwith slots (Z d, and the tongue T, hinged on the plate A and coranddesire to secure by the plate B, substantially as described and shown.
